Southwest China's Tibet Autonomous Region started construction of a planetarium with the world's highest altitude on Sunday, aiming to open up a window for Chinese people's never-ending exploration into the universe at the "roof of the world".

The planetarium, standing 3,650 meters above the sea level in Tibet's capital of Lhasa, covers an area of 11,571.79 square meters by the east wing of the Tibet Museum of Natural Sciences.

Planned to be completed in 2024, the planetarium is expected to receive over 100,000 visitors anually.

The planetarium will have the region's largest optical astronomical telescope, with a one-meter-diameter lens, and become a major regional base for astronomical research and public science education, according to the Science and Technology Department of Tibet.

The telescope will be jointly developed by the planetarium and the National Astronomical Observatories, and be used for variable star observation and time domain astronomy, according to the department.

Dubbed the "Roof of the World" on account of its position 4,000 meters above sea level, Tibet has superb clear skies, ideal for astronomical observation.
